[0038] Identification of the authenticity of Anguan Niuhuang Pills

[0039] The last step after the production and packaging of the pills is to store the anti-counterfeit microscopic images. The 10 square millimeters in the upper right corner of the box trademark is the anti-counterfeiting area. Tools are available to aid in quick positioning. Such as Figure 4 As shown in the positioning tool, there is a photography hole 2 on the main pallet 1, and there are baffles 3 perpendicular to it on the two adjacent sides of the main pallet 1. When the packing box is placed on the two sides of the main pallet 1 against the baffle When the board 3 is used, the anti-counterfeiting specific area is just on the photography hole 2, which is convenient for positioning and photography. Use a CCD photoelectric conversion micrograph to zoom in on a specific area, with a magnification of 30 times, and convert it into a video signal through a photoelectric conversion, collect it through a vid...

[0042] Anti-counterfeiting identification of famous paintings

[0043] For famous paintings identified by experts, a specific area of ​​0.1 square millimeters in the picture is magnified 200 times and photographed, and the digital microscopic image information processed by the computer is stored. At the same time, relevant information such as the identification date of the painting, the identification expert and the computer website of the stored anti-counterfeiting information are converted into barcodes and printed on the identification certificate of the painting.

[0044] During identification, according to the barcode of the painting, the computer URL of the stored anti-counterfeiting information is known, and information such as the location and magnification of the specific anti-counterfeiting area, computer processing process and other information are obtained through networking, and the anti-counterfeiting area is taken as the center, and an area of ​​2 square millimet...

[0046] Anti-counterfeiting identification of documents

[0047] After the certificate is produced, a specific area of ​​5 square millimeters is taken and enlarged 120 times for photography, and after computer processing, 30% of the center of the captured image is taken to extract image feature primitives for digital information storage. Digitize the certificate issuing unit, time and serial number, and microscopic image production information and print them on the certificate with barcodes.

[0048] During identification, the microscopic image production information and the stored microscopic image data are obtained according to the barcode information. A specific area of ​​5 square millimeters is magnified by 120 times, and microscopic image primitives are extracted after processing, and compared with stored data for identification.

Abstract

The method includes step: determining region for guarding against false, taking amplified image of the region, sanding digital image to computer; processing the digital image, picking up basic components of characteristic data; encoding compressing the picked basic components together with other tested information about the goods, storing encoded and compressed data to computer. Procedure of authenticating a goods includes steps: picking up characteristic data from goods to be tested; obtaining characteristic data from networked computer; comparing the picked characteristic data with characteristic data from computer so as to determine true or false of the goods. Microscopic characteristic of each goods is unique, and it cannot be copied. Thus, the method is reliable. Features are no any damage to goods to be tested so as to be suitable for cultural relics, paintings etc.

Description

(1) Technical field [0001] The invention relates to the field of anti-counterfeiting technology, in particular to an anti-counterfeiting method for a microscopic image on the surface of an object. (2) Technical background [0002] The current anti-counterfeiting methods are varied, such as printed images, fluorescent signs, heat-sensitive color-changing graphics, etc. However, the marks that can be recognized by the naked eye are easy to be imitated, and the reliability is low. [0003] The technology required for marking using laser holographic images is relatively high, and the production of randomly distributed micro-holes or pits as anti-counterfeiting information is more unique. Although this kind of logo is not easy to imitate, but because the logo and the object are integrated by pasting, they will inevitably be separated. Counterfeiters may reuse the real logo on the fake, making it difficult to distinguish. Therefore this class anti-counterfeiting method still has...
